| CHADS-VASc Score for Stroke Risk in Arial Fibrillation (CHA[2]S[2]-VASc) |
The EBMcalc module CHADS-VASc Score for Stroke Risk in Arial Fibrillation (CHA[2]S[2]-VASc) is available in EBMcalc Complete Edition.
This calculator evaluates the following Clinical Criteria:
- Congestive heart failure / LV dysfunction
- Hypertension
- Diabetes Mellitus
- History of stroke, TIA or thromboembolism
- Vascular disease (history of MI, PVD or aortic atherosclerosis)
- Age
- Sex
